` To all 'whom t may concern.' At e, Figs. 2 and 8 is also a graduating y Be it known that I, EDWIN SMITH, of damper, of the form there shown; and which Vhitestown, in the county of Oneida and may be drawn back in the position of the State of New York, have invented a new, dotted line z', or let remain at any interinedi- 60 5 useful, and Improved Stove called the ate point, thereby graduating the currents American Reverse Draft and I do hereof fire and smoke through the different pas- 1 ,by declare that the following isla full and sages which there connect with the pipe.

At f, Figs. 2 and 3 is another damper The nature of my invention, consists in which partly revolves so as to open or close 65 having dampers so arranged as to enable t-he passage in front of the lower oventhe operator to guide or turn the heat either closing it when in the position there shown; backward, or forward, over, under or around and opening it when in the position of the either o-ne or both of the ovens it contains; dotted line g. Hence it will be seen that or by merely changing the position of the when the damper at e Figs. 2 and 3 is drawn 70 dam-pers, convert any of the passages for back to the position shown by the dotted line the lire and smoke into chambers of heated z', and the two lower dampers closed, the fire air whenever the same may be desired; thus and smoke will pass directly to the pipe in increasing or decreasing the heat at pleasure, thedirection of the arrows a, a.
